Are SSDs the new RAM for boosting system performance?

    SSDs still aren't the equal of HDDs in at least one respect (other than densities): Flash Memory Survives 100 Million Cycles - IEEE Spectrum.

    Disagree. it's the random access time the provides the most performance from an SSD. This hasn't improved. The sustained read and write speeds have dramatically improved, but unless you are using your SSD for storage or trying to fill it to capacity in less then 2 minutes...it's not a huge advantage real world.

    But who is using SSD's for long term storage? I'm using it as an OS, app drive and it will be replaced with an upgrade long before it's write life ever expires.

    I was refering to reliability. HDD still have the edge when it comes to long-term reliability where lots of read/write activity is occuring. Also, there are plenty of examples of SSDs failing unexpectedly and prematurely. Reliability is certainly improving, but not equal to HDDs. Remember also that many devices are now coming with nothing but an SSD, so they are working as storage devices as well as OS/program devices.

    Lots of examples of HDD's failing prematurely too. I'd bet dollars to donuts, the majority of SSD's which failed were probably running the "Sandforce" controllers too. <--While the Sandforce controllers might have the best performance numbers, I stay away from them. Too many failures. Haven't had an Intel or Samsung drive let me down yet.

    There's no doubt that HDDs fail and, as with SSDs, it's probably more to do with the quality of components than anything else. Enterprise level SSDs are without a doubt very reliable, but at a significant cost difference to consumer SSDs, and it's the consumer that we're really discussing here, especially the average consumer who wants the cheapest products possible.

    Also, consumers usually want large storage capacity, for all their legally obtained songs, movies etc, so it's going to be a decision between something faster and more expensive, but with vastly lower storage capacity; or something a bit slower, but with vastly greater storage capacity. Usually, they choose the latter.

    I've found Fujitsu and Hitachi laptop drives to be very reliable over the years. I guess by their very nature, laptop drives are designed to be reliable.

    I have to dispute the reliability of laptop hard drives. When something with precise mechanical moving parts goes mobile in the hands of the person used to dropping their phone and picking it with it still working in three months, OOOOOOOOHHHHHHHHHHHHHHHHH yeah! Hard drive failure! There's also the fact as laptops are just mobile in their nature, plopping it down, closing the lid when the PC is on, moving it room to room when it's on, and being on the couch or a bed all will build up to hard drive failure. That's something I think most people don't understand, you can't do that.

    This is based on the fact that in the past two years, literally the ONLY type of hard drive I've had to run data recovery on were all the laptop 2.5 inch hard drives because the drive failed and a new one had to be used, and in a couple of cases, a SSD. In two years, I think I've gone through about 10 or so 2.5 inch drives that needed recovery, as well as a 2.5 inch drive from an external enclosure. This is partly the reason why I suggest to people in getting a SSD, not just because for performance, but for reliability against wear and tear of the PC.

    As long as your computer has room for 2 drives, you don't have to choose one or the other. Get a reasonable sized and priced SSD for the OS and Apps, and a large capacity drive for the storage of your files. Best of both worlds.

    The failing SSD are usually due to the controller and firmware, both are improving with each new gen.

    SSD Write Endurance 25nm Vs 34nm
    In this link, these guys are running write tests on various SSDs, the rumors of SSD fragility are exaggerated.

    Samsung 830 256GB Day 252

    (GiB) 6,282,908
    (TiB) 6,135
    (PiB) 6.03

    (Avg) 298.49 MB/s over the past 3400+ hours
    And still going.

    (GiB) 6,282,908 = 6,746,221 GB
    (TiB) 6,135 = 6,745 TB
    (PiB) 6.03 = 6.789 PB

    The average desktop user writes between 7-10 GB worth of information per day.
    You can figure out your average writes, and do the calculations.

    Using 20 GB/day is 7.3 TB/year.
    6,745 TB / 7.3 TB/year is 923.9 years.

    A quick extrapolation for a 128GB Samsung SSD is 462 years.

    I have five portable PCs (laptop/notebook/tablet variants), one has a busted screen, one has a blown BIOS and the three others all work and are used regularly (the tablet attached to the dash of my 4WD when off road). I also have two portable storage devices, one with a busted screen (dropped on to rocks) and the other working fine (bounced all over the placed). None in all of their lives have had a hard disk failure.

    Not many laptops/notebooks/tablets have room for two drives, the ones that do, are likely a substitute for a desktop. A know a lot of people and they don't own or want a desktop, they want a laptop or tablet for all of their computing needs. I'm not against SSDs, but for many people, they simply are not worth getting as a regular HDD is ample for their needs.

    The one reason I bought the Samsung 830 was because of its reputed reliability vs the likes of OCZ which seems to have a reputation for failure. But a lot of people still buy OCZ.

    From my experience, once you drop a laptop a couple of times while running, you end up putting it on a course of hard drive failure. It may not happen right away, in six months, or in a year; but it will happen. And happen it will....

    I would like to have a dual hard drive/SSD type set up on a laptop, but again, the wear and tear of using the laptop will affect the hard drive. It may be best to invest in flash memory, either SSD, SD, or USB.
